Maserati Quattroporte M156 Headlights

Maserati Quattroporte (M156) utilizes a sophisticated lighting system that evolved significantly between the pre-facelift (2013–2017) and the facelift (2018–2023) models. For a luxury specialist, distinguishing between the Bi-Xenon and the Full LED Matrix units is critical for correct fitment.

1. Pre-Facelift (2013–2017): Bi-Xenon with AFS

These units feature a large single projector lens and are characterized by the curved LED daytime running light (DRL) strip along the bottom.

• Technology: Bi-Xenon (HID) High/Low beam.

• AFS (Adaptive Front-lighting System): Features a swiveling projector that follows steering input.

• Common Part Numbers: 670002014 (Left), 670002013 (Right).

• Aesthetics: Chrome internal shrouds (Standard) or Dark/Black shrouds (found on “Nerissimo” or Sport trims).

2. Facelift (2018–2023): Full LED Matrix

Introduced in late 2017 for the 2018 model year, these are a significant technological leap. They are identified by a “sharper” internal design and no visible circular projector lens.

• Technology: Full LED Matrix Beam.

• Features: Glare-free high beam (selectively dims LEDs to avoid blinding oncoming traffic) and integrated LED indicators.

• Common Part Numbers: 670104712 (Left), 670104711 (Right).

• Fitment Note: These are not plug-and-play for 2013–2017 cars without a specialized conversion harness and central computer (ECU) coding.
